This study documents the performing and teaching career of Armando Ghitalla (1925-2001), and describes his pedagogical approach with an emphasis on understanding his approach to teaching embouchure. It includes as appendices a comprehensive discography of his solo, chamber, and orchestral recordings, a listing of his solo performances with the Boston Symphony Orchestra, a selected list of former students, and copies of his advanced flexibility and transposition studies.The personal interview served as the primary source of data for this study. The subject, Armando Ghitalla, participated in an in-depth interview with the author which was recorded and transcribed. Subsequent data was gathered from former students through the use of an open-ended questionnaire. Follow-up interviews were held with several of the respondents. Previously published articles, interviews, reviews, and an unpublished recording of a trumpet clinic were also consulted.Ghitalla was a member of the Boston Symphony Orchestra for twenty-eight years, serving as solo trumpet of the Boston Pops Orchestra from 1951-1965 and principal trumpet of the Boston Symphony Orchestra from 1965-1979. He was active as a virtuoso trumpet soloist and had a distinguished career as a trumpet professor following his retirement from the Boston Symphony. His success as an orchestral performer, solo performer, and noted pedagogue distinguish him from many of his contemporaries. / School of Music
